THREE PHASES OF LABORATORY TESTING

THREE PHASES OF LABORATORY TESTING;-

1) Preanalytical :- 

All procedures/processes that occur before the specimen is actually tested. Includes patient preparation,accurate paperwork and data entry, appropriate specimen collection, processing, storage and transportation.

2) Analytical :- 

All procedures/processes involved in the testing of the specimen. This includes the way the testing instrument was prepared and maintained, how the testing supplies were stored, appropriate training of the personnel performing the test, and quality control to ensure that the testing methods are working properly.

 

3) Postanalytical :- 

All procedures/processes that affect how the test results are handled when the analysis has been completed. These may include review and analysis of the results by the person performing the test, appropriate follow-through on extremely high or low results, how the results are recorded (in a computer or on paper, etc.) phone calls, report printing, report sorting, appropriate fax procedures, charting procedures within an

office, physician review procedures, contact with patient if necessary for follow-up.

● quality control (QC):-  

measures, which are in place to validate the test reagents/kits, the testing process, and

training of the laboratory personnel performing the test.

• Postanalytical Phase: 

The postanalytical phase of laboratory testing includes the processes associated with the recording and reporting of laboratory results,

storage and/or disposal of specimens after testing, and provider and patient notification of test results. Even if the other two phases of testing occur without any exceptions, if this phase isn’t handled appropriately, then the overall experience will not be a positive one,

and may negatively affect patient treatment.
